turntables oi such machines on which soundrecords of disk shape are sup'porteil during the operation of reproducing the recorded sounds.

In the exploitation of talking machines and sound-records therefor it has found desirable to so consiruct the machin or certain of the parts thereof to precluci the use Wlill such machines GI recorcls 0" other than a particular make the objec in doing this being lo insure so ilie seller of e 0 machine a reesonable'piofis from a? records for use ilierfeon such will uc him to sell the machine as low price Heretofore, it has been sought to ccompizsn machines which support the disk soumlrecords during the ieprofleeing operet u, with one or more projections of peculiar shepe'so that only recoids formed i0 col-- IQSQOIld with such projections will: lie upon the lurntables in posiliou for ire aroclucing. These turntables es heretofore consuccessful in attaining the desirced iesulvb. Thus, turnmess have been provided with or more integral projections of sins ss-seclion on the upper feces thereof c s to A 1. through corresponfiing openings iii v sound-recoi'cls; but as these turntables ere mede of cast metal, sharp slow s hammer on the projection will. cause it to break ofi practically flush with surface of the turntable, and thereafter standard disk records may be used thereon. if jections of lergei cross-sectional cree- Weiss employed, such that they could be 0e l moved by putting'ihe turntables iu and cutiing the projections down te the le el of the faces of the turntables.

My invention is directed to the prov i of a turntable of an improveu construciiou, such that with it the use of sound-records of lie desired make is other limo i prevented.

The preferred embodiment of th invention is illustrated. in the accompanying drawin "whicli eiicuually l" igui'el an elevation of s talking me- 6 1 1 section of the tutu Ti; and Fig. il s udrawings, a milking mach ne or u well-known type i illustrated, 1 WW7 be on stood that the invention is eppiioebie geneuill lo all machines for "eproducing i iozc (.lisi: F011i1(l1'(3fi1'l3.

s we raised turntable Wiiil the shaft 6.1: motor.

With the form of turntable herein. clescribed, sound-records of annular form'may .be employed, these resting upon the upper face of the portion 7 with the raised portion 8 passing through the central opening therein. The peripheral shape of the raised portion 8 may be changed as desired to limit the machine to use with a particular style of records only. In any case, the turntable cannot be so changed as to adapt it for use with standard records. This is due primarily to the provision of the hollow raised portion 8 having its under surface flush with or above the upper surface of the annular portion 7. It will be seen that if the raised portion 8 were cut down in the effort to adapt the turntable for use with standard records, the central portion of the turntable would be severed from the outer portion and the turntable rendered useless.

Having now described my invention, What I claim as new therein and desire to secure by Letters Patent is as follows l. A talking machine comprising a motoradapted to be mounted upon the motor-shaft of the machine, said turntable having an outer portion and an inner raised portion and the under surface of said raised portion being .above the upper surface of said outer portion, substantially as set forth.

3. A turntable for a talking machine having an outer annular portion, an inner raised portion integral therewith and having its under surface above the upper surface of said outer annular portion, and a member secured Within a central opening in said raised portion, said member being formed. to

coact with the motor-shaft of the machine to support the turntable, substantially as set forth.

4. A turntable for a talking machine adapted to be mounted upon the motor-shaft of the machine, said turntable having an outer portion and an inner raised portion and the under surface of said raised portion lying in substantially the same plane as the upper surface of said outer portion, substantially as set forth. v

5. A turntable for a talking machine adapted to be mounted upon the motor-shaft of the machine, said turntable having an outer annular portion and an inner raised portion integral therewith and the under surface of said raised portion being above the upper surface of said outer portion, substantially as set forth.
